| 摘 要： | 为提高华龙一号核电机组ZH-65型蒸汽发生器抗震性能，提出了一种新型的蒸汽发生器支承方案，即对蒸汽发生器上部支承釆用连接拉杆与液压阻尼器结合的结构形式，并针对总体设计方案和连接拉杆的热膨胀相容性进行了设计研究。相比原有二代加核电机组蒸汽发生器上部支承，本文所设计研究的上部支承在设备重量、焊缝数量、安装调试难度等方面，均有大幅优化；可有效减少支承载荷，最大减少幅度约为24%；可降低蒸汽发生器接管焊缝载荷，最大降低幅度约为28%。

| Abstract: | In order to improve the seismic performance of ZH-65 steam generator of HPR 1000 nuclear power plant, a new support scheme of steam generator is put forward, that is, the structure of connecting rod and hydraulic damper is used for the upper support of steam generator, and the overall design scheme and the thermal expansion compatibility of connecting rod are designed and studied. Compared with the original steam generator upper support of the second generation plus nuclear power unit, the upper support designed and studied in this paper is greatly optimized in terms of equipment weight, number of welds and difficulty of installation and commissioning; It can effectively reduce the supporting load, and the maximum reduction range is about 24%; The weld load of steam generator nozzle can be reduced, and the maximum reduction range is about 28%. |
